SEAT AND DESK FASTENING.

SPECIE'ICATION forming part of Letters Patent No. 332,839, datedDecember 22, 1885.

Application filed August 22, 1885. Serial No. 175,057. (No model.)

To all whom it may concern:

-Be it known that I, FRED LINCOLN SANDS, a citizen of the UnitedStates,residing at Lyndon, in the county of Whiteside and State of Illinois,have invented certain new and useful Improvements in Seat and DeskFastenings; and I do hereby declare the following to be a full, clear,and exact description of the'invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention pertains to seat and desk fastenings, and has more especialreference to means of detachably attaching school and ball furniture, sothat the same can be readily detached from the floor and removed in caseof fire, or when the space is desired temporarily to be used in othermodes.

In all seated halls, and particularly in school-rooms, an attachment ofthe furniture to the floor is a necessity, to preserve the properrelative location of such furniture, and in case of desks to give thelatter sufficient immobility. Heretofore such furniture has been affixedby screws-a mode which rendered the detaching thereof impracticablewithout considerable labor, and, where the building was on fire, theconsumption of too much time.

In my invention it is thedesign to provide a mode of attaching suchfurniture which will permit the detaching thereof with very littleeffort and in a very short time, and to render such attachmentadjustable.

As my invention has no reference to the furniture itself, I do not deemit essential to show or describe the latter further than is necessary toexhibit the attachment thereof.

In the drawings, Figure 1 is an attachment exhibiting one mode ofapplying my invention. Fig. 2 is a detail perspective.

A is the foot of the seat or desk, having the divergent horizontalprojections a a a, adapted to rest upon the floor. A is the leg. B isthe attachment, consisting of the three joined or united sides GD E, andadapted to be screwed or otherwise fastened to the floor. Spaces b areprovided under the sides 0 and D, into I which two of the projections aof the foot A are respectively placed. To the side 0 is pivoted thelever F, in condition to be oscillated vertically. The third projectiona of the foot A projects under the lever F, when the latter is broughtdown to the horizontal position, in which position the leveris clampeddown upon such foot and held in position by an oscillating hook, G,pivoted to the open end of the side E, so as to project over and engagenotches d on the upper side of the lever F. The eye at the lower end ofthe hook G is parallel with the lever F, so as to permit such hook, whendisengaged, to be thrown back off such lever and allow the latter to beraised. The lever F is so pivoted that when it is thrown upward it fallsoutside of the side O. The projections a of the foot A have a centralradial rib on their upper surface, and such foot is forced under thesides 0 and D until the ribs abut, respectively, against the undersurfaces of such sides, and when the lever F is brought down tightlyupon the third projection a the foot A is held rigidly and immovably tothe floor. \Vhen it is desired to release the foot A, the lever F issprung downward slightly to loosen the hook G, when the latter is thrownoff from the lever F, such lever thrown forward, and the foot Awithdrawn laterally from the attachment B.

As the locking devices are usually made of cast-iron, there is in thecooling thereof some variance in the size of the parts; and to avoid anylooseness arising from variance in the relative size or location of theparts, it is essential that the leverFbe adapted to be lockedadjustably, and thus held down rigidly upon the foot A, whatever therelative height of the latter. by providing the series of notches d onthe upper surface of such lever, and the hook G can be forced into suchone of said notches d as will effect the desired rigidity; and if fromthe shrinkage of the floor, such notch shall cease to produce therequisite tightness, the hook G can be forced into some notch d nearerthe point of such lever, and increased tightness thus effected. It isimportant that there be not the slightest play or looseness of the footA.

This is accomplished in my invention What I claim as my invention anddesire to 2. The combination of the attachment B, secure by LettersPatent of the United States, the foot A, lever F, and hook G,substantially is as shown, and for the purpose described.
